Description of Phyllocnistis selene Brito & Moreira, 2017 was based on five specimens from the Centro de Pesquisas e Conservação da Natureza Pró-Mata (CPCN Pró-Mata) São Francisco de Paula municipality, Brazil. The male holotype is deposited at DZUP and has the following labels (separated by forward slash symbols, Fig. 4V): / Phyllocnistis selene Brito & Moreira HOLOTYPE #m / 236–22 Brasil, RS Promata 0 7.03.2014 GRPMoreira&RBrito #m / DZ 33.403 /. The holotype genitalia is slide-mounted in Canada balsam (GRPM 50– 121). According to the original description, the paratypes are as follows: one male (LMCI 263–18) with genitalia on slide (GRPM 50–122) and one female (LMCI 210–34), deposited at DZUP (33.413, 33.423, respectively); another male (LMCI 263–26) with genitalia on slide (GRPM 50–123) and one female (LMCI 263–28) are deposited at MCTP (57.620 and 57.621, respectively). Forewing length. 2.15 mm (n=2). Diagnosis (Figs. 3V, S 1; Tab. 2). Dorsal forewing: ground color light gray. lf thin, light brown, without borders, emerging from the base of costal margin and running straight to center, connecting to fused tf 1 –tf 2. Transversal fasciae light yellow with light brown borders. tf 1 short, restricted to costal section. tf 2 crossing the wing entirely, merged with tf 1. At distal region (III), a light yellow blotch formed by fusion of tf 3 + tf 4. At the center of this blotch there is another small black blotch. As preceded by a light gray stripe. Costal and apical strigulae typical. The shape of lf, in association with pattern of corresponding fusion with tf 1+ tf 2 are unique for this species compared to other Neotropical Phyllocnistis. Geographical distribution (Fig. 5). Records are restricted to type locality, in São Francisco de Paula municipality, Rio Grande do Sul state, Brazil, at 900 m of altitude. Natural history. According to the original description, mines are transparent, serpentine shaped and usually followed by a brown trail of feces. Initially they are thin, increasing in width along larval ontogenesis, and corresponding paths may cross each other forming blotches. The mines are found on the abaxial and adaxial leaf surfaces. The egg is deposited next to the petiole, and usually only one larva feeds per leaf. The cocoon is covered with silk, constructed at the border of the leaf, provoking a leaf wrinkling. Larvae were found in the field in the months of March and April, suggesting that this species is active as leaf mining during late summer and early autumn. Host plant(s). Drimys angustifolia Miers (Winteraceae). Examined material. Holotype male and one specimen, with no sex identified. Brazil: Rio Grande do Sul - São Francisco de Paula (Centro de Pesquisas e Conservação da Natureza—Pró-mata), 900 m, 07.III.2014, G.R.P. Moreira & R.

A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

Universality of jamming of nonspherical particles
No full textAmorphous packings of nonspherical particles such as ellipsoids and spherocylinders are known to be hypostatic: The number of mechanical contacts between particles is smaller than the number of degrees of freedom, thus violating Maxwell's mechanical stability criterion. In this work, we propose a general theory of hypostatic amorphous packings and the associated jamming transition. First, we show that many systems fall into a same universality class. As an example, we explicitly map ellipsoids into a system of "breathing" particles. We show by using a marginal stability argument that in both cases jammed packings are hypostatic and that the critical exponents related to the contact number and the vibrational density of states are the same. Furthermore, we introduce a generalized perceptron model which can be solved analytically by the replica method. The analytical solution predicts critical exponents in the same hypostatic jamming universality class. Our analysis further reveals that the force and gap distributions of hypostatic jamming do not show power-law behavior, in marked contrast to the isostatic jamming of spherical particles. Finally, we confirm our theoretical predictions by numerical simulations
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Abstract: Lateral sinus thrombosis (LST) is an uncommon, but life-threatening complication of both acute and chronic otitis media. There is some evidence that acquired or hereditary prothrombotic disorders are risk factors for LST. The aim of this work was to evaluate the role of thrombotic screening, anticoagulant therapy or prophylaxis in patients with either acute or chronic otitis media and LST. The medical records of five children hospitalized at Pediatric Hospital Bambino Gesu of Rome because of acute or chronic otitis media complicated by mastoiditis and LST were reviewed. All children underwent laboratory workup for hypercoagulability. All the five children were found to be heterozygote for the C677T MTHFR mutation and a child presented also heterozygosity for factor V Leiden mutation. They have been successfully treated with anticoagulant therapy without sequels. Children with acute or chronic otitis media may have a prothrombotic tendency that becomes clinically evident because of the inflammatory state. Patients with a family and/or personal history of thrombosis and/or thrombophilic conditions need anticoagulant prophylaxis also in the absence of clear signs of LST. Treatment with low molecular weight is successful in patients with LST. Blood Coagul Fibrinolysis 23:158-163 (C) 2012 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins

Adult male, 2.3 mm long, mounted on a slide (coordinates 28 º08´34 ´´N / 16 º 26´21 ´´W; 3 m depth) [DBAULL NE/TAS 12]. Additional specimens (two males and four females) in R. Riera collection. Meristic data. Abrigos subtidal: May, 2 males (Holotype and m 4), March, 1 male (m 2), December, 1 male (m 3) and 3 females (f 3, f 4 and f 5); Cristianos subtidal: November, 1 female (Allotype), April, 1 female (f 2). Etymology. The specific name refers to the Sshaped spicules of this species. Description. Male: Body slender, attenuating towards both ends. Head slightly round and not set off. Cuticle smooth, without marked punctations nor lateral differentiation. Amphids are 50 % of the corresponding body diameter in width, multispiral of 3.5 turns, located at 5 m from the anterior end. Buccal cavity conical and small, with three small teeth, difficult to discern. Inner labial setae inconspicuous. 6 outer labial setae 0.3 cephalic diameters long and 4 cephalic setae 1.6 cephalic diameters long, situated at the median part of the head. Subcephalic setae 14 m long, located at 28 m from the anterior end. Pharynx slender and cylindrical. Ventral gland and nerve ring not seen. The reproductive system is diorchic, with two opposed testes, difficult to discern. Spicules 3.6–5.2 anal diameters long, slender, Sshaped, without marked capitulum. Gubernaculum 0.8–0.9 anal diameters long, slender, proximally compressed. An elliptical plaque present at the distal end of the gubernaculum. 35 precloacal supplements, each penetrated by a duct; posteriormost precloacal supplement situated at 45 m from the cloaca. Tail 2.4–4.4 anal diameters long, cylindrical and filiform in most of its length, with a swollen posterior tip. 2 subterminal setae 15 m long, located at 5 “m from the posterior tip. Spinneret well developed. Female: They are similar to males. Total body length slightly shorter than in males (1.7–2.3 mm). Tail longer than in males (5–6 anal diameters). The reproductive system is didelphic, with two outstretched ovaries, almost inconspicuous. Vulva located in the posterior half of the body, at the level of 53.9–55.2 % of the total body length. Discussion. Paracomesoma sigmoidalis new species is closely related to P. inaequale Jensen & Gerlach, 1977, in general body shape, but the latter species differs in having a longer tail, 6.3–7.5 anal diameters in males and 8–9 anal diameters in females, and the number of precloacal supplements (25–32 in P. inaquale and 35 in P. sigmoidalis). P. sipho (Gerlach, 1956) and P. hexasetosum (Chitwood, 1937) resemble P. sigmoidalis new species although they differ, like not as P. inaequale, in the presence of a larger tail and the number of precloacal supplements (30 in P. sipho and 40 or more in P. hexasetosum). Moreover, P. sipho has more developed amphids (80 % cbd) and P. sigmoidalis new species can be distinguished from the latter two species by having subcephalic setae more anteriorly located.
